---------------------------------------------------------------------

Topic:

Updated libpng packages are available that fix a buffer overflow vulnerability.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - i386
Red Hat Linux 7.0 - i386
Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386

3. Problem description:

The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. PNG is a bit-mapped graphics format similar to the GIF format.

Unpatched versions of libpng 1.2.1 and earlier do not correctly calculate offsets, which leads to a buffer overflow and the possibility of arbitrary code execution. This could be exploited by an attacker creating a carefully crafted PNG file which could execute arbitrary code when the victim views it.

Packages within Red Hat Linux, such as Mozilla, make use of the shared libpng library. Therefore, all users are advised to upgrade to the errata packages. For Red Hat Linux 8.0 the packages contain libpng 1.2.2 which is not vulnerable to this issue. For Red Hat Linux 6.2, 7, 7.1, 7.2 and 7.3 the packages contain libpng 1.0.14 with a backported patch that corrects this issue.

4. Solution:

Do you need help?

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
